The analysis of blood samples is carried out using ELISA in an immunology and molecular biology laboratory. Results: 71% of people present concentrations equal to or greater than 20 mIU/ml. In the KAP strategy, the highest rating was in the practical compo-nent with 50.8%, followed by knowledge with 40%, an acceptable score, and attitudes 27.7% with an insufficient score. Within this survey, 38% of the participants know the routes of transmission for Hepatitis B, 51% present the complete vaccination scheme, and 75.4% report not having been involved in an accident with biological risk. Conclusion: KAP strategy, knowledge about Hepatitis B; was represented in the acceptable rating, insufficient attitudes, and outstanding practices
